Point of sale system

ABSTRACT

A point-of-sale system is a dual-screen stand assembly that includes a merchant terminal and a consumer terminal. The merchant terminal and the consumer terminal can be mated together in a fixed position to form a single unitary stand, or can be separated from each other in a separated position with each terminal serving as its own separate stand. The merchant terminal supports a merchant computing device and is oriented in a merchant-facing direction. The consumer terminal is detachably mated to the merchant terminal and supports a consumer computing device that is oriented in a consumer-facing direction. The point-of-sale system also includes a card reader as part of the customer terminal to perform a payment. The card reader is configured to accepting swipe cards, chip cards or contactless (EMV or NFC) payments.

BACKGROUND

Consumers can interact with merchants to conduct various financial payment transactions. For example, a consumer can conduct a transaction with a merchant at a point-of-sale system using cash, a transaction card, or other transaction instrument. Conventional systems can include expensive and bulky specialized equipment and financial transaction electronics, as may include a card reader for payment cards (e.g., debit or credit cards), a cash drawer, monitors, keyboards, and various other electronic devices. Oftentimes, however, this equipment can be costly and large, requiring additional space and resources. Further, in retail stores where space is limited, a merchant may not require all components that come with a conventional point-of-sale system or at least may find it desirable to piece together a modular or mobile system to streamline the checkout experience. Further still, merchants may find approaches to conducting a financial transaction using conventional systems burdensome, where during a transaction, if a customer pays by credit card, the merchant has to enter a transaction amount and the merchant or the customer has to swipe the credit card in the card reader. Further, many transactions require that the customer sign a physical receipt, electronically approve a transaction, e.g., by pressing an approve button on a user interface, electronically sign for the transaction, e.g., with a stylus or finger on an electronic signature capture device with a touch sensitive pad, or enter an authorizing personal identification number (PIN), many of which techniques require additional financial transaction electronics and time.

DETAILED DESCRIPTION

Systems and methods in accordance with various embodiments of the present disclosure overcome one or more of the above-referenced and other deficiencies in conventional approaches to conducting financial transactions. In particular, in accordance with various embodiments, approaches provide for a point-of-sale system configured to enhance financial transactions by streamlining and simplifying components needed in performing a financial transaction. The point-of-sale system includes a secure enclave for accurately receiving and handling secure data provided into the point-of-sale system.

For example, in accordance with various embodiments, the point-of-sale system is a dual-screen stand assembly that includes a merchant terminal and a consumer (or “customer” as used interchangeably herein) terminal. The merchant terminal and the consumer terminal can be mated together in a fixed position to form a single unitary point of sale system including a merchant facing terminal and a consumer facing terminal, or terminals can be separated from each other and arranged in a separated position with each terminal being physically independent of the other. The merchant terminal supports a merchant computing device and is oriented in a merchant-facing direction. The consumer terminal is detachably mated to the merchant terminal and supports a consumer computing device that is oriented in a consumer-facing direction. The point-of-sale system also includes a card reader as part of the customer terminal to perform a payment. The card reader is configured to accept swipe cards, chip cards (Europay, MasterCard and Visa hereinafter “EMV”) or contactless (low power Bluetooth or near-field communication, hereinafter “NFC”) payments.

The point-of-sale system is configured to present an interface to the merchant terminal. Information regarding an item for sale or a service being provided is received at the merchant terminal. The information is then sent to the consumer terminal and a check-out procedure is initiated. The payment total is sent to the consumer terminal and a payment card can be inserted into the consumer terminal. The consumer terminal has a display that is specific to the type of payment card used so that when a swipe card is inserted, the display provides the appropriate signature, and when a chip-type card is inserted, an appropriate PIN display is provided on the consumer terminal. A secure enclave can be provided to securely store entries that are, for example, entered into a secure enclave of a portable computing device at the consumer terminal. Payment information acquired from the payment card, and the appropriate verification thereof, is provided to a payment system. Payment confirmation is received from the payment system, which can be displayed on one or both of the merchant terminal and the consumer terminal.

Other advantages, variations, and functions are described and suggested below as may be provided in accordance with the various embodiments. Reference is now made to FIG. 1 illustrating an example point-of-sale system 100 including a first terminal 110 including a first computing device 115 (e.g., a tablet computer, a mobile phone, etc.). The computing device can be integrally provided as a component of the first terminal to form a unitary structure or a computing device provided by a manufacturer that is separately provided and inserted into the terminal by the appropriate user. The computing device can include, for example, a processor, a touch-screen display, and a wireless local area network receiver, a physical interface for electronic communication, and a physical interface to receive power (which can be integrated with the physical interface for electronic communication, e.g., in a Universal Serial Bus (USB) connector or other proprietary connector). The first terminal 110 is detachably mated to a second terminal 120.

The computing device can run a merchant application or other financial transaction software that can provide functionality to facilitate a point-of-sale such as by enabling payment transactions. For example, in accordance with various embodiments, the merchant application can be downloaded and installed on the computing device. The software can be configured to operate with a card reader, where an individual can complete a financial transaction by swiping a magnetic stripe card through the card reader or dipping a chip-type card into the card reader that is connected to the computing device. In this example, the financial transaction can be any transaction that involves receiving or sending payment from one person or entity to another. The magnetic stripe card can be, for example, a credit card, a debit card, or other types of payment authenticating pieces having a magnetic stripe storing information sufficient to carry out the financial transaction. In accordance with various embodiments, the card reader can be integrated into the consumer terminal to allow the consumer to properly provide the payment card. However, in some embodiments, a separate card reader can be used, such as a miniaturized card reader that is easily connectable to the computing device.

The first terminal 110 and second terminal 120 can be in communication with each other via wired or wireless link. In this example, the first terminal 110 represents a terminal used by a merchant conducting a transaction at a point-of-sale system with a consumer using, for example, a payment card via the second terminal 120. It is noted that although a payment card is used in some embodiments, transactions can also be conducted through a card-less payment account that is linked to the payment card. Other transactions include person-to-person, account-to-account, electronic cash, among others. It should be further noted that although a credit card is shown to conduct transactions, approaches described herein apply to other types of financial payment instruments including, for example, debit cards, chip-type cards, and card-less payment accounts. As described, in conventional point-of-sale systems, the equipment can be costly and large, requiring additional space and resources. Further, in retail stores where space is limited, a merchant may find it less desirable to have such a large system. Accordingly, in accordance with various embodiments, approaches provide for a streamlined point-of-sale system with a merchant terminal and a consumer terminal detachably mated from the merchant terminal. It is further desirable to securely process and store entries securely entered into the consumer terminal.

The second terminal 120 supports a second computing device 122. The second computing device 122 is shown integrally formed within the second terminal 120 to provide a single one-piece structure. In some embodiments, another tablet provided separately by the same or another manufacturer, can be inserted into the second terminal 120. The second terminal 120 includes a secure enclave 124 for securely processing and storing entries into the second terminal 120, as described in greater detail herein. The second terminal 120 also includes a card reader 126 configured to read both magnetic swipe cards and chip-type cards. Although shown here as a single hybrid slot capable of reading both card types, two readers, in the form of two separate slots, can be provided with one “swipe” slot for receiving a magnetic swipe-type card and a “dip” slot for receiving a chip-type card.

Reference is now made to FIG. 2 illustrating an example schematic diagram of components of each terminal in the point-of-sale system in accordance with an embodiment. The point-of-sale system 200 includes a merchant terminal 210 and a consumer terminal 212. The merchant terminal 210 includes a SoC (System-on-chip) processor 220 and associated flash memory 222 and RAM 224. A USB-A port 226 is provided for connecting other devices or components to the merchant terminal 210 as appropriate. A USB+Power port 228 is provided connected to a 5-port USB Hub 230 for various peripherals associated with a point-of-sale system, including a receipt printer, cash drawer, barcode scanner, scale, keyboard, USB-Ethernet dongle/USB mifi, and other point-of-sale peripheral components known in the art. While both a USB-A port and a USB+Power port are separately identified, such should not be considered limitation. Merchant terminal can have any number of USB ports, and the ports can be of any suitable characteristics. A power supply 232 can be provided as power through the hub H3 230 via connector 228 on the merchant terminal 210. A debug module 236 is provided for appropriate debugging of the merchant terminal 210 and the various components thereof. An audio amplifier 238 is provided and a speaker 240 for providing the appropriate audio for the merchant terminal 210. A display 242 can be connected to the processor 220, for example a 13.3-inch LDC display having a resolution of 1920×1080 IPS 166 PPI. The display 242 provides the interfaces and outputs to the merchant terminal 210 to be viewed by a merchant. A wifi receiver 244 is in communication with the processor 220 to perform the wireless communication, for example, with the consumer terminal and other point-of-sale system components, or for example a payment system. And a USB port 246 is provided for detachably connecting the merchant terminal 210 to the consumer terminal 212. The term “detachably” is intended to refer to the ability for the merchant terminal to be connected to the consumer terminal but also configured to being detached from the consumer terminal when desired for storage, upgrades, or other uses. This mating between the terminals can be through wired connections shown or wirelessly, in some embodiments.

The consumer terminal 212 includes a SoC processor 250 connected to the micro USB 252 for communication with the merchant terminal 210. A Power Management Integrated Circuit (PMIC) 254 is in communication with the micro USB connector 252. A PMIC is an integrated circuit for managing power requirements of the host system. A debug module 256 is provided for the processor 250 for the appropriate debugging of the consumer terminal 212 and the various components thereof. The processor 250 is coupled to flash memory 258 and RAM 260 for appropriate storage and processing of data. An audio amplifier 262 and speaker 264 is provided for any audio for the customer on the customer terminal 212. A display 266 is provided, such as a 7-inch LCD touch-screen display having a resolution of 1280×800 IPS 216 PPI. The display 266 provides interfaces and the outputs of the point-of-sale system to the consumer terminal 212. A secure enclave 270 is included in the consumer terminal 212. The secure enclave includes a secure MCU 272, an anti-tamper battery 274, and a secure debug module 276. The MCU 272 receives inputs from the Magnetic Stripe Reader (MSR) 278 which are read by a magnetic head reader 280. Inputs are also received from EMV contact 282 and processed by an EMV contact block 284. Inputs from a contactless EMV are received from an EMV contactless antenna 288 and processed by the EMV contactless block 286. The contactless antenna 288 is dual-use in some embodiments, and configured to receive input from EMV cards and NFC (near field communication) cards, as well as other NFC devices, such as smart phones or other devices configured to process payment transactions. All inputs received by the consumer terminal at the touch controller 292 (for example, as entries into a payment application or a register-buddy application in communication with the merchant terminal), are sent to the secure enclave and the multiplexer 290 determines if the entries should go directly to the non-secure processor, or if further processing (for example, encryption) is needed, and the entries are sent to secure processor. A multiplexer 290 receives inputs from a touch controller 292 and directs inputs received in a non-secure portion of the GUI to the non-secure processor, and directs inputs received in a secure portion of the GUI to the secure processor. In some embodiments, the main processor on the merchant terminal and the consumer terminal will each run their own operating system (including possibly two different copies of the same operating system, different versions of the same operating system, or different operating systems altogether, etc.).

FIG. 3 illustrates an example process for conducting a financial payment transaction in accordance with various embodiments. In the example process 300, a merchant interface is presented 310 and information regarding an item or a service being purchased is received 312. Information is sent to a consumer terminal 314 and a check-out procedure is initiated 316. The payment total is sent to the consumer terminal 318 (for example, displayed on display 266) and the payment card is received in the consumer terminal 320. The type of card (swipe, EMV, NFC, etc.) being used is determined 322. A payment interface is presented to the consumer on the consumer terminal based upon the type of payment card used. Accordingly, for example, if a magnetic-stripe swipe-type card is used, then 324 an interface is presented to the user to allow for signature entry, and if a chip-type card is used, then 326 an interface is presented to the user to allow for PIN entry or other secure verification of the use of the card. Payment information is provided to a payment system 328 and a payment confirmation is received at 330. This can occur via Wifi (244) or direct connection via USB (for example 228 in FIG. 2 ) in some embodiments. Note that the payment confirmation could also be a confirmation that the payment has been denied. The merchant interface is notified of the completed transaction 332. The consumer interface can also be notified of the completed transaction in some embodiments.

FIG. 4 illustrates an example diagram of flow of data between the components of the point-of-sale system in accordance with an embodiment. The flow of data between the merchant terminal 410, the consumer terminal 412 and the payment system 414 are shown. The consumer terminal 412 includes the flow of data to and from both the non-secure processor 416 and the secure processor 418. The non-secure processor 416, for example, can be the processor 250 of FIG. 2 , and the secure processor, for example, can be the secure MCU 272 in FIG. 2 .

In accordance with the example diagram, a merchant interface is presented 420 at the merchant terminal 210. The item or service information is received 422 at the merchant terminal 410 and then provided to the non-secure processor 416 to display the information 424 on the consumer terminal 412. The check-out procedure 426 is initiated by the merchant terminal 410 once all items and/or services have been entered. The payment total 428 is then provided to the non-secure processor 416 to be displayed on the consumer terminal 412. A payment card is received 430 and the type of card is determined 432. If the payment card is an EMV card, the payment information is encrypted 434 by the secure processor 418. The encrypted payment information 404 is then sent to the non-secure processor 416 to be provided either directly 440 to the payment system 414, or indirectly send the payment information 438 via the merchant terminal 410 to the payment system 414. A payment confirmation is generated 442 by the payment system 414 and this payment confirmation is provided 444 to the merchant terminal 410.

Having now described various example embodiments of the point-of-sale system using in a point-of-sale transaction, some example environments for conducting a financial transaction at a point-of-sale system will now be described. Other environments and applications of the point-of-sale system should be apparent to those ordinarily skilled in the art.

FIG. 31 illustrates an example environment for conducting a financial transaction at a point-of-sale system in accordance with various embodiments. In this example, the exemplary environment 3100 includes a merchant payment system 3102 for processing transactions between a customer and a merchant. The merchant payment system includes, for example, a data processing server 3104 and a payment server 3106. The data processing server can be implemented as computer programs on one or more computers in one or more locations, in which the systems, components, and techniques described herein can be implemented. The operation of the payment server is described below in reference to FIG. 32 . The example environment also includes computing devices, e.g., transaction registers or other point-of-sale systems, corresponding to the merchant 3110 and 3111.

As described, the point-of-sale systems 3110 and 3111 can include the computing device, where the computing device can be coupled to or in communication with the merchant payment system through a data communication network 3108, e.g., the Internet. These devices each generally include a memory, e.g., a random access memory (RAM), for storing instructions and data, and a processor for executing stored instructions. The devices and can each include one or more components, e.g., software or hardware, that are operable to send and receive requests, messages, or other types of information over the network. Some examples of computing devices include personal computers, cellular phones, handheld messaging devices, laptop computers, personal data assistants, tablet devices, and the like.

The network 3108 can include any appropriate network, including an intranet, the Internet, a cellular network, a local area network, a wide area network, or any other such network, or combination thereof. Components used for such a system can depend at least in part upon the type of network, the environment selected, or both. Protocols and components for communicating over such a network are well known and will not be discussed herein in detail. The devices and the referral system can communicate over the network using wired or wireless connections, and combinations thereof.

Each of the computing devices is configured to send to the merchant payment system respective financial data that corresponds to a financial transaction that was processed by the computing device. The financial data can include, for example, data stored in a financial payment card, e.g., Track 1 data, receipt email addresses, and information describing a card-less payment account. Other examples of financial data that can be captured includes purchase data, e.g., an itemized listing of purchases, card mix data, geolocation data indicating a geographic location of a particular transaction, online/offline card data, data describing the merchant, e.g., merchant category codes (MCCs), and any type of data that is received upon a customer's authentication into a social network.

FIG. 32 illustrates an example of an environment 3200 for implementing a payment service network. Although a mobile device environment is described for purposes of explanation, different environments may be used, e.g., a web-based environment, to implement various embodiments. The example environment includes a payment system 3208, which can be implemented as computer programs on one or more computers in one or more locations, in which the systems, components, and techniques described below can be implemented. The example environment also includes a user device 3202 and a merchant device 3205.

The user device and the merchant device can each be a computer coupled to the payment system through a data communication network 3250, e.g., the Internet. The user device and the merchant device each generally include a memory, e.g., a random access memory (RAM), for storing instructions and data, and a processor for executing stored instructions. The user device and the merchant device can each include one or more components, e.g., software or hardware, that are configured to respectively determine a geographic location of the user device or the merchant device, using, for example, various geolocation techniques, e.g., a global positioning system (GPS). Further, the user device and the merchant device can each be any appropriate device operable to send and receive requests, messages, or other types of information over the network. Some examples of user devices include personal computers, cellular phones, handheld messaging devices, laptop computers, personal data assistants, tablet devices, and the like.

The network can include any appropriate network, including an intranet, the Internet, a cellular network, a local area network, a wide area network, or any other such network, or combination thereof. Components used for such a system can depend at least in part upon the type of network, the environment selected, or both. Protocols and components for communicating over such a network are well known and will not be discussed herein in detail. The payment system, the merchant device, and the user device can communicate over the network using wired or wireless connections, and combinations thereof.

As used in this specification, a financial transaction is a transaction that is conducted between a customer and a merchant at a point-of-sale. When paying for a financial transaction, the customer can provide the merchant with cash, a check, or credit card for the amount that is due. The merchant can interact with a point-of-sale device, e.g., merchant device, to process the financial transaction. During financial transactions, the point-of-sale device can collect data describing the financial transaction, including, for example, the amount of payment received from customers.

In some implementations, the payment system is configured to accept card-less payment transactions from customers, e.g., the customer. As used in this specification, a card-less payment transaction is a transaction conducted between the customer and a merchant at the point-of-sale during which a financial account of the customer is charged without the customer having to physically present a financial payment card to the merchant at the point-of-sale. That is, the merchant need not receive any details about the financial account, e.g., the credit card issuer or credit card number, for the transaction to be processed.

In some embodiments, before conducting card-less payment transactions, the customer typically creates a user account with the payment system. The customer can create the user account, for example, by interacting with a user application that is configured to perform card-less payment transactions and that is running on the user device. When creating a user account with the payment system, the customer will provide information of the customer, data describing a financial account of the customer, e.g., credit card number, expiration date, and a billing address. This user information can be securely stored by the payment system, for example, in a user information database. To accept card-less payment transactions, the merchant typically creates a merchant account with the payment system by providing information describing the merchant including, for example, a merchant name, contact information, e.g., telephone numbers, the merchant's geographic location address, and one or more financial accounts to which funds collected from users will be deposited. This merchant information can be securely stored by the payment system, for example, in a merchant information database.

The payment system can be configured to perform card-less payment transactions. The payment system can include one or more servers that are configured to securely perform electronic financial transactions, e.g., electronic payment transactions, between a customer and a merchant, for example, through data communicated between the user device and the merchant device. Generally, when a customer and a merchant enter into an electronic financial transaction, the transaction is processed by transferring funds from a financial account associated with the user account to a financial account associated with the merchant account.

The payment system is configured to send and receive data to and from the user device and the merchant device. For example, the payment system can be configured to send data describing merchants to the user device using, for example, the information stored in the merchant information database 3212. For example, the payment system can communicate data describing merchants that are within a threshold geographic distance from a geographic location of the user device, as described in this specification. The data describing merchants can include, for example, a merchant name, geographic location, contact information, and an electronic catalogue, e.g., a menu, that describes items that are available for purchase from the merchant.

In some embodiments, the payment system is configured to determine whether a geographic location of the user device is within a threshold geographic distance from a geographic location of the merchant device. The payment system can determine a geographic location of the user device using, for example, geolocation data provided by the user device. Similarly, the payment system can determine a geographic location of the merchant device using, for example, geolocation data provided by the merchant device or using a geographic address, e.g., street address, provided by the merchant. Depending on the implementation, the threshold geographic distance can be specified by the payment system or by the merchant.

Determining whether the user device is within a threshold geographic distance of the merchant device can be accomplished in different ways including, for example, determining whether the user device is within a threshold geographic radius of the merchant device, determining whether the user device is within a particular geofence, or determining whether the user device can communicate with the merchant device using a specified wireless technology, e.g., Bluetooth or Bluetooth low energy (BLE). In some embodiments, the payment system restricts card-less payment transactions between the customer and the merchant to situations where the geographic location of the user device is within a threshold geographic distance from a geographic location of the merchant device.

The payment system can also be configured to communicate with a computer system 3216 of a card payment network, e.g., Visa or MasterCard, over the network, or over a different network, for example, to conduct electronic financial transactions. The computer system of the card payment network can communicate with a computer system 3216 of a card issuer, e.g., a bank. There may be computer systems of other entities, e.g., the card acquirer, between the payment system and the computer system of the card issuer.

The customer operating the user device that is within a threshold geographic distance of the merchant can interact with a user application running on the user device to conduct a card-less payment transaction with the merchant. While interacting with the user application, the customer can select the merchant, from a listing of merchants, with whom the customer wants to enter into a card-less payment transaction. The user can select the merchant, for example, by selecting a “check in” option associated with the merchant. The user device can communicate data to the payment system indicating that the customer has checked in with the merchant. In response, the payment system can communicate data to notify the merchant device that the user has checked in. A merchant application running on the merchant device can notify the merchant that the user has electronically checked in with the merchant through a display screen of the merchant device.

Once checked in, the customer can collect, or request, items that are available for purchase from the merchant. When the customer is ready to enter into the card-less payment transaction, the customer can, for example, approach a point-of-sale for the merchant and identify him or herself. For example, the customer can verbally notify the merchant that the customer wants to enter into a card-less payment transaction and can provide the merchant with the customer's name. The merchant can then interact with the merchant application to select the customer, from a listing of customers that have checked in with the merchant, to initiate a card-less payment transaction for the items being purchased by the customer. For example, the merchant can determine a total amount to bill the customer for the items being purchased. The customer can verbally approve the total amount to be billed and, in response, the merchant can submit a request for a card-less payment transaction for the total amount to the payment system. In response, the payment system can obtain, for example, from the user information database, data describing a financial account associated with a user account of the customer to which the total amount will be billed.

The payment system can then communicate with the computer system of a card payment network to complete an electronic financial transaction for the total amount to be billed to the customer's financial account. Once the electronic financial transaction is complete, the payment system can communicate data describing the card-less payment transaction to the user device, e.g., an electronic receipt, which can, for example, notify the customer of the total amount billed to the user for the card-less payment transaction with the particular merchant.
